Features • Designed expressly for Switch-Mode Power Supply and PFC (power factor correction)applications • Industry-benchmark switching losses improve efficiency of all power supply topologies • 50% reduction of Eoff parameter • Low IGBT conduction losses • Latest-generation IGBT design and construction offers tighter parameters distribution, exceptional reliability
Benefits • Lower switching losses allow more cost-effective operation than power MOSFETs up to 150 kHz(“hard switched” mode) • Of particular benefit to single-ended converters and boost PFC topologies 150W and higher • Low conduction losses and minimal minority-carrier recombination make these an excellent option for resonant mode switching as well (up to >300 kHz)
